*** Bug 328591 has been marked as a duplicate of this bug. ***
I don't see how this relates to Bug 328591. There's no problem running Firefox or Icecat and I could equally give kernel logs for other processes including bash and the kernel process sync.
I see some patches about fixing nfs deadlocks that are now in kernel version 2.6.34. Can you test with the latest gentoo-sources, which is gentoo-sources-2.6.34-r2 at this time and let me know the outcome?
Is this fix also in gentoo-sources-2.6.35 ?
Yes
Using gentoo-sources-2.6.35 doesn't fix my issue... (original Bug 328591)
Still happening with 2.6.35-r5. workrave seems to be a common culprit: INFO: task workrave:25778 blocked for more than 120 seconds.

On both ppc64 (32-bit userland) & x86_64.
workrave writes to $HOME/.workrave by default and doesn't seem to do any locking. So this may be a result of $HOME being shared and two machines racing over the same files.
I still get this every time I run firefox or thunderbird. The app fails to get a lock on something and hangs.
Can you please test with gentoo-sources-2.6.36
Still problematic on 2.6.36 for me.
Please submit this upstream at http://bugzilla.kernel.org and post the URL back here.
https://bugzilla.kernel.org/show_bug.cgi?id=14891 Probably a good idea of others who have similar issues give some more debug information (strace output or the like)
Sorry. I meant to link this bug. https://bugzilla.kernel.org/show_bug.cgi?id=22992
If you think that bug is a accurate representation of your issue, we will watch that bug.
I am also seeing this on 2.6.32-gentoo-r24. The last know good version of the kernel was 2.6.31-gentoo-r6.
